How Many Square Feet Does A Bundle Of Shingles Cover
One bundle of shingles covers roughly 33 square feet of roof. Some manufacturer bundles will cover slightly less and will range from 28 up to 33 square feet.
For some brands and types, the square feet per bundle may vary. A bundle of one type of shingle may have one extra than a bundle of the same type and brand. Some bundles will indicate a shingle minimum on the package. If that is the case, the square footage of the bundle will also vary, but not by much and it will always be at or around of 100 square feet.
What Is A Bundle Of Shingles
A bundle of shingles is one package of shingles. Shingle manufacturers will package their bundles so that several usually 3 or 4 will add up to 100 square feet. A bundle of shingles will contain anywhere from 15 to 29 shingles, depending on the type and size.
It is important to note that there is not a uniform number of shingles per bundle. The number of shingles in a bundle will vary tremendously depending on if you have typical 3-tab versus laminated or other specialty shingles.
A bundle can only be so big. They are designed so that the average person can pick them up and move them, so you will never have one bundle drastically larger or heavier than a bundle for a different type of roof shingle.
Initially, a bundle of shingles was supposed to cover one piece of roof sheathing 32 square feet. And three bundles would add up to 100 square feet. The advent of laminated shingles, which are much thicker than standard 3-tab, have created bundles with a total area that is less than the original 32 square feet.
How Much Does A Bundle Of Shingles Weigh
A bundle of shingles weighs anywhere from 60 to 80 pounds. Most bundles are in the 70-pound range. A bundle must be light enough to be handled by your average-sized adult. Therefore, you will not find bundles that way anywhere beyond 80 pounds.
Very thick laminated architectural shingle bundles may weigh less if it requires 4 bundles to make a square of roofing. In that case, each bundle will cover a smaller area and will thus weigh less. However, the majority of shingle bundles will have a similar weight.

What If You Have A Steep Roof
To measure a steep roof, use one of the following alternate methods:
Calculate the roof length by measuring the exterior walls plus the overhang for the length of the house parallel to the ridge.
Next, throw a rope over the ridge and mark it where it meets each eave. This will give the width dimension to use in figuring your area. This should be done on each roof section containing a horizontal ridge.
Determine the roof area by using a mathematical formula that accounts for the roof length, total span, and roof pitch:
What Is A Square In Roofing
A roofing square is the amount of roofing material required to cover 100 square feet of roof. When calculating the number of shingles you need to cover your roof, youll calculate the area in terms of squares. Therefore if you have 2100 square feet of roof, youll need 21 squares of roof material.
A square of shingles is the number of shingles needed to cover a square of roofing. Whereas a bundle of shingles can vary in square footage, a square of shingles is always 100 square feet. This makes it easier when purchasing roofing materials since manufacturers will package 3 or 4 bundles of shingles to add to an even square.
A square in roofing is always 100 square feet. This refers to the square footage on the roof surface. It doesnt necessarily have to be a perfect square and is a quick way to calculate the quantity of roofing material that youll need for your job.
Youll always need more shingles than youd think to cover a square of roofing. Even if a shingle is 12 wide, some of that is covered by the shingle on top of it. Therefore, only about 6 to 8 of each shingle is showing. Thus, for standard 3-tab shingles, you may end up with 80 or more shingles in one square of roofing.

How Many Bundles Of Shingles Do I Need For A 10×12 Shed
To calculate the amount of shingle bundles needed for a 10×12 shed, you first have to calculate the square footage of the roof.
Lets say this shed has a gable roof running parallel to the long end of the shed. The shed also has a roof overhang of 1 all around. Therefore the length of one side of the roof is 14.
The pitch of this roof is 4:12. A rough estimate of the width of one side of the roof is just a bit over 5 say 53, which is 5.25 feet. Add a foot of overhang and you get 6.25. Multiply this by 14
Multiply the two and you get 87.5 square feet. Multiply that number times two and you get 175 square feet your total roof area.
Now you need to find out how many bundles of shingles is required for 175 square feet of roofing. Divide 175 by 100 to find out how many squares of roofing you have. This equals 1.75. We know that each square of roofing requires 3 bundles of shingles, so 3 bundles of shingles times 1.75 roofing squares equals 5.25 bundles of shingles.
You still have .25 of roof leftover. It would be prudent to purchase one extra bundle of shingles to ensure you cover your entire area and to replace any damaged shingles in the future.
Thus, it takes 6 bundles of shingles to properly cover the roof of a 10×12 shed with a gabled roof and a 1 overhang around all sides.

Measuring The Roofs Pitch
The incline or pitch of a roof can be easily measured with a level, tape measure, and a pencil. The roofs pitch is the number of inches the roof rises in 12 inches. Therefore, mark off 12 inches on the level and place it down horizontally against the roof rafter.
Next, measure vertically from the 12-inch mark on the level straight up to the underside of the rafter, as illustrated below. That measurement is the number of inches the roof rises in 12 inches.
Some homes will have roofs with multiple pitches. Porches and dormer windows, for example, can have a different pitch from that of the rest of the house. For an accurate surface area measurement you should make note of these additional structures.
Using the table below, lookup the pitch/es and make a note of the number/s in the multiplier column. This multiplier number will be used to multiply the surface area calculation that SketchAndCalc will provide.
Finding The Total Roof Area
Once the area of the roofs footprint is known, the overall roof area can be found by accounting for the roofs pitch. The pitch of the roof is the rise over a 12-inch run. Use our roof pitch calculator to find the pitch of your roof.
Next, multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area.For example, a 4/12 pitch roof that is 100 square feet:
100 × 1.054 = 105.4ft2

How Many Shingles In A Bundle
Im starting to think about re-shingling my roof as its got some age and the shingles are looking a little rough. Since my roof is a couple of rectangles, its easy to calculate the surface area. I figured I could estimate how many shingles I needed and the total cost. But before I calculated the cost, I still needed to know how many shingles in a bundle?
For traditional asphalt 3-tab roof shingles, there are 26 pieces in a bundle. Architectural shingles will have around 21 shingles per bundle for similar square footage, as they are larger than standard 3-tab shingles.
Depending on the shingle manufacturer, the number of shingles in a bundle can vary widely. Since shingle dimensions vary so much, it is often helpful to have a shingle calculator to determine the number of pieces and bundles youll need for your project.
In this article, well take a look at a shingle calculator that helps you with precise estimates for your roofing material, as well as various examples of roofs and how to determine shingle bundles and squares for a new, shingled roof.

One of the biggest challenges for experienced builder and novices alike is accurately estimating materials for a construction projectespecially for roofs, because they can be difficult to access for taking measurements.
But dont fretIn this excerpt from my book Roofing with Asphalt Shingles, I describe three reliable methods for determining the area of a roof, plus Ive included tips for estimating the number of extra shingles youll need for waste, overlaps, and starter shingles.
Note: be sure to take your time and double-check your numbers when calculating the quantity of shingles, underlayment, flashings, and other materials needed for yourroofing project. The more accurate your estimates, the less time youll waste waiting for material deliveries during the project.
How Do You Estimate The Cost Of Metal Roofing
When ordering supplies it is important to estimate materials correctly to allow for an efficient installation process. Estimating the amount of metal roofing materials you need starts with estimating the square footage of the roof itself. Measure the length and width of each roof section in feet then multiply together to get he square footage.
Divide 533 square feet by 2 feet and the result is 266.5 linear feet. Next do the same with the 3-foot material and the result is 177.66 linear feet. Calculate the number of pieces we will need in both the 2-foot wide material and the 3-foot wide metal roofing.

Calculate The Square Footage Of Your Roof
After considering the slope and complexity of your roof, youre ready to learn how to calculate the square footage of your roof.
To get a rough estimate for your roofs square footage, youll use this equation:
For example, if you have an easy up and over, walkable gable roof and a house that measures 56 feet lengthwise and 28 feet widthwise, your calculation will look like this:
56′ x 28′ = 1,568
1,568 x 1.3 = 2,038
Using this equation wont be 100% accurate, but knowing your roofs square footage is a great jumping-off point to learn how much youll have to invest in your replacement. After getting your roofs rough square footage, put that number in our free Roofing Calculator to get an idea on the cost of your new roof.
How Big Is A Square In Roofing
The calculations above will give you the total number of square feet of the roof area.
As you have noticed in the roofing industry however, the surface of the roof is being measured in squares. This refers to the roof area that measures approximately 100 square feet.
Therefore: 1 Square in Roofing = 100 square feet
Now, in order to determine how many squares are there on the gable roof for example, all you need to do is divide the total square footage by 100.
- Total square footage from Example 2 above: 28,000 sq. ft.
- Number of squares for 2 planes: 28,000 sq. ft. ÷ 100 = 280 squares
This means that both planes of the roof will require 280 squares of shingles. A three-tab shingle, which is most commonly used, is packed in 3 bundles per square.

Varying Roof Styles Make The Term Roofing Square More Common
Another reason that you cant always divide square footage by 100 to get the number of square is because every roof shape and style is different
For example, measuring a gable roof is fairly straightforward, but measuring a gambrel or mansard style roof can be a bit more complicated. Waste becomes a major factor when measuring more intricate roofing types like mansard and hipped roofs. Waste happens when shingles need to be cut to fit tight spaces . They are not always nailed in even rows along the roof deck.
With more complex roof types, you quickly realize that not every square foot of measurement is created equal! Overall, the phrase roof square helps bridge the gap for projects both simple and complex.
